Questions: Relationships

Copied from my other account because I'm stupid and chose the wrong gender there:

Since the moment I've met him, he's had my undivided attention. If we weren't coworkers, I would have immediately asked him out.

At work, we constantly pick on and roast each other and laugh about inside jokes. A coworker noted our relationship as being obnoxiously sibling-like, but my boss was sure we'd end up dating.

Just recently though, I had to move away for work. At my going-away party, I became certain he treats me differently from others. We were all drinking so things are fuzzy, but I know he was glued to my side the entire night. And it was easy to catch eye-contact with him because he was looking at me a lot. At one point we had a conversation which became suggestive, and I was sure it was going somewhere, but then he said "i like ya, i love ya, but it would be weird". I dropped it because I didn't want to make him uncomfortable. After that it was back to picking on each other and having a good night with friends. Then, when we were the last two at the bar, he picked me up, carried me to the roadside, hugged me, said he'd miss me, and ran to his taxi. I was left confused on the sidewalk before heading home.

Then the night before I left, after saying goodbye to everyone, he drove me to my hotel. We hugged and said we'd miss each other, and just before I walked into the hotel lobby, he called out again to say he'd miss me. He sounded a little emotional.

I've been a wreck since then. Not knowing how he feels is messing with me. I can't figure out if we're just friends and he sees me as a sister, or if he feels the way I do. All I know is that I'm significant to him somehow.

Since I'm now a 4 hour plane trip away, I'm not sure if it's a good idea to confess. I'd get closure and, if he was open, I'd do long-distance in a heartbeat. But if he doesn't reciprocate, I've done something selfish and upset him with the burden of my feelings.

Maybe one of you can see this clearer.
